Deleting File and Directory in JUnit

Question

I\'m writing a test for a method that creates a file in a directory. Here\'s what my JUnit test looks like:

  @Before
  public void setUp(){
      objectUnderTes         


        

Answer 1

This is how I usually clean up files:

@AfterClass
public static void clean() {
    File dir = new File(DIR_PATH);
    for (File file:dir.listFiles()) {
        file.delete();
    }
    dir.delete();
}

Your directory must be empty in order to delete it, make sure no other test methods are creating more files there.

Ensure you are closing the FileWriter instance in a finally block.
